1. A dual-mode fluid connector (150), comprising:
a hollow connecting element (310), comprising a chamber (411) inside the hollow connecting element (310), wherein a protuberant block element (415) is arranged on an inner surface of the chamber (411);
a material tube (322), positioned on the hollow connecting element (310) and connected through the chamber (411);
a cleaning tube (324), positioned on the hollow connecting element (310) and connected through the chamber (411);
a head portion (330), positioned on one terminal of the hollow connecting element (310) and comprising a connecting opening (431), wherein the connecting opening (431) is connected through the chamber (411) and capable of being detachably connected to a material container (130);
a rear portion (340), positioned on another terminal of the hollow connecting element (310) and comprising a through hole (441), wherein a track (443) and a block wall portion (447) are arranged on an outer surface of the rear portion (340), and the block wall portion (447) is positioned on one side of an end section of the track (443);
